Al Franken, truly a farce to be reckoned with, only “understands” science presented from the AGW true believers! No reputable scientist, even those who feel humans have a significant responsibility, has stated ALL the recent warming (which is significantly less than the early “warming”)is attributable to humans! What… did all natural sources of CO2 suddenly stop? Maybe trees are holding their collective breath?
Romm, if Franken is the best spokes-idiot you can come up with, it’s a sad day for you fanatics!
